In our own analysis, we found out that the JDK-internal implementation of XML Digital Signatures also supports the feature, although in an implicit way, the implementation is not public API and hidden from the user. As the entire XML-DSIG implementation in the Sun/Oracle JDK, it uses a version of the Apache Santuario implementation internally.
We finally settled for Jaxen because it was easier to integrate than Santuario.

您查看过 Apache Santuario 库吗？
它附带了一个实现 XML Signature XPath Filter v2.0 的类：
TransformXPath2Filter此处列出了更多实现（尽管我还没有检查其中任何一个）：
Did you have a look at the Apache Santuario library?
It comes with a class that implements XML Signature XPath Filter v2.0:
TransformXPath2FilterFurther implementations are listed here (though I haven't checked any of these):
感谢 0xA3。互操作性报告列出了以下两个支持 XPath Filter 2 的开源库：
在我们自己的分析中，我们发现JDK 内部实现 XML 数字签名也支持该功能，尽管以隐式方式实现不是公共 API 并且对用户隐藏。作为 Sun/Oracle JDK 中的整个 XML-DSIG 实现，它在内部使用 Apache Santuario 实现的一个版本。
我们最终选择了 Jaxen，因为它比 Santuario 更容易集成。
Thanks to 0xA3. The interoperability report lists the following two open source libraries that support XPath Filter 2:
